Not that I've heard of yet but somebody's bound to try it. I've seen that big A-10 fly at the QSAA Giant scale rally back in the 90s and lets just say there wasn't a lot of excess power there, it was a huge airplane to push around on those fans. The nacelles are huge, you could go with a larger fan if there was one. Well there is, the Byron Byrojet, some guys in Arizona are converting them with some Hacker outrunners. Don't recall the wattage their getting but probably more static thrust than a ramtec would do since it's a larger fan. I don't know if you have molded nacelles or you're doing an all balsa project but if balsa then you could change the design to suit the byron.

I believe Josh Harel's original design used his 3 bladed cut down master airscrew and custom designed 8" housing for power. If you ran that on maybe some outrunners that might be even better but I don't know what the flight speed would be. I heard the glow motors were throwing prop blades so that's why the guys in Denver who built the ones I saw went with the glow fans.

yeah its a tall order right now for ramtec and dynamax stuff in regards to motor and ESC's . Bruff is messing with Byro stuff right now with some good result's, and parts for conversion are supposed to be available soon from EJF.com.

I have the Giant Jets F-16A semi kit from Josh Harel and I think a twin Byron conversion of his A-10 would be Perfect,and relatively inexpensive.

The Dynamax and Ramtec are a little on the small side for this one IMHO

From the looks of the plans that I have you could EASILY loose a few pounds just by substituting foam or hard balsa in alot of non structural areas....it calls for plywood EVERYwhere

I am working towards this build by getting the EDF setup and finding out it's capabilities on a sport jet before Diving into a huge build like the F-16 or in your case the very cool ,but very large A-10.
